Surprising infection inducing mechanism found in bacteria
Date:5/18/2010

and thus commence a replication and packaging cycle. The island is then capable of transference and of making other harmless bacteria turn virulent.

The new mechanism discovered by scientists is of great importance for the development of new treatments for diseases caused by bacterial toxins. The pathogenicity island studied is a prototype of a new family of virulent DNA recently discovered which also can be transferred to other species of bacteria such as Listeria monocytogenes, responsible for a large number of intoxications.

Less than a year ago, the research group led by Dr Jordi Barb from the Department of Genetics and Microbiology at UAB published an article in Science on the antibiotic resistance mechanism in bacteria ["The SOS Response Controls Integron Recombination". Science. Vol. 324 (2009)]. "With the two articles in Nature and Science we have basic knowledge of the mechanisms used by bacteria to cause infections. This "doublet" in science not only demonstrates the quality of research being carried out at universities in our country, but also the possibility of creating applications for the treatment and prevention of bacterial infections", says Dr Jordi Barb.
